FILTER Application filed June 12, 1913. Serial No. 773,365.

' Specification of Letters Patent.

Patented July a, rare.

The object of my invention is to produce,

a simple, eficient and serviceable filter which may be manufactured atsmall cost, and at the same time produce a filter of such constructionthat the filtering element can be readily removed for cleansing,repairing or reversing as may be desired. 1 attain these objects by theconstruction illustrated in the accompanying drawings in which Figure 1,is an elevation of the assembled device. section of the case, theinternal mechanism being shown in elevation for the purpose of moreready comprehension. Fig. 3, is a display illustrative of the componentparts of the filtering element, and the manner in which they are stackedor arranged.

Like numerals denote like parts in each of the views.

1, is the body portion of the case. which is provided with the hexagonalhub 2, and the threaded nipple 3, projecting therefrom.

a, is the cover or cap portion of the case, and is secured thereto byscrew threading as shown at 5. The cover portion of the case i, isprovided with a hexagonal hub 6, which is provided with a female threadas shown at 7.

8, designates the conical-shaped springs, which compress and hold thefiltering element in position. A

9, is the gauze screens between which the filtering disks 9", areconfined and compressed.

The body portion and the cover portion respectively 1, and 4, of thecase, are provided with internally projecting hubs 10, for the purposeof centralizing the small ends of the springs 8, the larger ends of saidsprings, being of such diameter as Wlll neatly fill the casediametrically.

The gauze screens 9', are made of wire gauze or perforated metal and arepfsuch diameter as will neatly fill the case diametrically, as arelikewise the filtering disks 9",

Fig. 2, is a view in longitudinal which may be formed of any suitableloosely woven or felted material, or any other applicable material orsubstance.

in assembling the element 9, ll prefer to start with two screens, then adisk of filtering material and then a screen alternately until asuitable number are stacked to suit the requirements, preferablyfinishing with two screens.

The springs 8, are of such length that they are considerably compressedwithin the case, when the said case is screwed together.

To assemble the device, one of the conical shaped springs 8, is placedwithin the body portion 1, of the case, the small end of the springencircling the hub 10, then the as sembled element composed of alternatescreens and filtering disks 9' and 9", is placed in position within thecase and resting upon said spring. The second spring 8, is next placedin position with the large end thereof resting upon the said filteringelement 9, and thecoverd, is next placed in position so that the smallend of the uppermost spring 8, encircles the hub 10, which projectsinwardly from the said cover, and the said. cover screwed to place. litwill be readily understood that when necessary to replace or repair thefiltering element, it can be easily and readily accomplishedbyunscrewing the cover portion and removmg the internal parts. To operatethe device, it is only necessary to install it either in a pipe-line orattach it to a faucet through which the liquid to be filtered is passed.The device is especially adapted to filtering fuel for hydrocarbonengines, being'im stalled in the pipe-line between the supply tank andthe carbureter.

One of the advantages of the foregoing construction, where the device isinstalled in the fuel-feed system of hydro-carbon en-' gines, especiallyon motor-cycles, automobiles &c., is that the severe vibration to whichit is subjected, does not materially afi'ect the filtering element, onaccount of the resiliency of the conical springs between which it isheld, again the compression of the filtering material between thesprings, causes the edges of said filtering element to expand and fitthe cylindrical case perfectly, thereby precluding the possibility ofleakage around the edge thereof. I am aware that a spring has been usedto hold such construction being shown in patent'to Murphy N 0. 638,742,therefore I do not broadly claim such construction, but I am not awarethat a filtering element has been compressed and held resiliently withina cylindrical case between two springs.

Therefore what I claim and desire to secure by Letters Patent is Afilter consisting of two cup-like members screw-threaded together toform a hollow cylindrical case, a screw-threaded tubular connectionlocated centrally of, and extending outwardly from the end of each ofthe cup-like members, and communicating with the interior thereof, adisk-like filter- 7 ing element diametrically located within saidcylindrical case, and approximately central of the length thereof,conical springs in said case and seating against the' ends thereof, andarranged to bear against the opposite sides of and compress and expandsaid element, and to hold the said element resiliently in position, allarranged and operating substantially as shown and for the purpose setforth.

In testimony whereof, I have hereunto set my hand at Los AngelesCalifornia this ninth day of May 1913;

vJAMES R. PROPER. In presence of Gno. D. MOCLDRE, H. D. SOHROEDER.
